# PureLibro vs 読書尚友

The clearest difference is rating: PureLibro at 4.6 against 読書尚友's 4.0. PureLibro also leads on ads (none vs shown) and review sentiment (77% vs 50%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. PureLibro sells 6 in-app purchases, starting at $0.99 per month and 読書尚友 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
